Ksubi to Gap jeans size
The short answer
Ksubi 2 is Gap 00 by the two brands' own charts. 10 of 11 Ksubi sizes land on a different label at Gap.
Both brands publish the body waist each size is cut for, so every row matches a waist, not a tag.
On 1 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.
